Presented at the
International Symposium on Formal Methods for Components and Objects

In this paper, we present a framework for formal modeling
and verification of service-based business processes with focus on their compliance to external regulations such as Segregation of Duties (SoD) or privacy protection policies. In our framework, control/data flow is modeled using the exogenous coordination language Reo. Reo process models are designed from scratch or (semi-)automatically obtained from
BPMN, UML or WS-BPEL specifications. Constraint automata (CA), a semantic model for Reo, provide state-based representations of process workflows and enable their verification by means of model checking technology. Various extensions of CA make it possible to analyze time-,
resource- and Quality-of-Service (QoS) process models.
